More fixing for fade-outs.

When a window is destroyed, always override the fade out so that the finish_destroy_win function can be called.
When a ConfigureNotify event is processed on an unmapped window, don't set the clipChanged = True.  Fixes unmap->configure causing flashing during the fade-out.
